We put thirty spokes to make a wheel: But it is on the hole in the center that the use of the cart hinges. We make a vessel from a lump of clay; But it is the empty space within the vessel that makes it useful. We make doors and windows for a room; But it is the empty spaces that make the room livable. Thus, while existence has advantages, It is the emptiness that makes it useful.
LaoziAs long as we have hope, we have direction, the energy to move, and the map to move by. We have a hundred alternatives, a thousand paths and an infinity of dreams. Hopeful, we are halfway to where we want to go; hopeless, we are lost forever.
Laozi
